L293D Motor Driver IC
L293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive in either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. It is also known as Dual H-bridge Motor Driver integrated circuit (IC). The l293d can drive small and quiet big motors as well
